'ATTACHING DEVICE FOR RECEPTACLE BAILS.

'Application fi1ed`March 25, 1926.' Serial No. 97,287.

Our invention relates to the class of fastening devices for attachng balls to receptacles.

It is often desirable, and in some cases bail fasteners, therefore, which comprise' nietallic Studs, rivets, bolts, pins, staples and the like, passing through the staves to the interior of the vessel are unavailable.

The special object of our invention is to meet this difliculty; and this we accomplish by providing a novel bail-attaching device, no part of which is exposed to the interior of the vessel.

Although this object finds its special use in thus avoiding interior metallic exposure, it is to be understood that our invention, without regard to and aside from such object, contemplates the provision of a simple, effective and strong bail-fastening, functioning not only to carry the vessel, but also to tighten its stave assembly.

`With these objects in view our invention consists primarily of a bail-fastening assembly comprising a suspension member, a vessel-embracing hoop with which one end of the suspension member is connected, and a bail-member with which the other end of the suspension member is connected.

It further consists in said assembly when applied to a vessel of' inverted frustum shape, the embracing hoop of which assembly tends to tighten under the load.

It consists further in thenovel structure of the suspension member, its disposition with relation to the exterior surface of the vessel, and its engagement with the hoop, all of which we .shall hereinafter fully describe by reference to the accompanying drawings,

" it being understood that changes in detail and arrangement may be made without departing from the spirit of our invention as defined by the claims hereunto annexed.

In the drawings- Fig. 1 is a view in elevation of a vessel with our invention'applied thereto. Fig. 2 is a sectional view of a stave longitudinally of the kerf. Fig. 3 is a view in elevation of the suspension member. Fig. 4 is a sectional View on line 4-4 of Fig. 2. Fig. 5 is a view similar to Fig. 4 with a hoop overlying the kerf. Fig. 6 is a transverse section takenon line 6-6 of Fig. 7. Fig. 7 is a View in detail of one of the suspension members received in the kerf, hooked around the stave, and connected with the bail.

1 is a vessel composed of staves with chimed-in heads as usual. In the form shown, the vessel has the shape of an inverted cone-frustum, so that its embracing hoops 2 tighten by being driven upwardly.

3 is the bail. 4 is the suspension member of our fastening assembly. It consists of a metallic link slightly arcuate in its length, and provided with an eye 4:' on its upper end and with a hook 4" on its lower end.

In the exterior of opposite staves, near their upper ends, and traversing the plane of the uppermost hoop 2, is made a kerf 5 which is arcuate, being deepest at its middle, its ends merging in the surface of the stave. This kerf is relatively shallow and does not extend through the stave.

In assembling the fastening, the suspension link 4 which initially is not bent to form the lower end hook 4", is passed down within the kerf 5, behind the hoop 2 until the eye 4' of said link rests upon the upper edge of the hoop; and by reason of the arcs of both kerf and link the lower end ofthe link readily emerges from the kerf below the hoop, and said end is then conveniently bent 'outwardly and upwardly to form the hook 4:" which engages the hoop, and thus the link is tightly seated on the hoop, by its eye and hook. With the eye of the link, the bail 3 is engaged.

It will now be seen that the load is carried by the hoop, and that when the vessel is of the shape shown the hoop is tightened under the load. It will also be seen that no part of the bail-fastening is exposed within the vessel; and, finally, it is noted, that the fastening is one which can readily be applied, and is efficient.

We claim V 1. In combination With a receptacle having on its exterior at opposite sides a kerf, with a depth less than the thickness of the receptacle wall, an embracing hoop crossing .said kerfs, a bail member, and a suspension link seated in each of said kerfs behind the hoop, said links .each provided on its upper end with an eye for resting on the upper edge of the hoop and eaeh atits lower end engaging the lower edge of the hoop, and the eyes receiving the bail member, said gooves and said links being arcuate.

2. In conbination With a 'eoeptaele having on its exterior at opposite sides a kerf, With a depth less than the thiekness of the reoeptaele Wall, an embracing hoop crossing said kerfe, a bail member, and a suspension link seted in each of Said kerfs behind the hoop, said links each provided on 'its upper end With an eye for resting on the upper edge of the hoop and each atitsloWe' end engaging the lower edge of the hoop and the eyes receiving the bail membei'.

In testimony whe'eof We have signed our names to this specifioation.
